From the Preface: "This booklet is a brief presentation of the orthodox side of the controversy between the Conservatives, or Fundamentalists, and the Liberals, or Modernists. The question at issue is: Is the Bible the word of God, by Divine inspiration given, or a 'collection of myths'? The Conservatives and Fundamentalists accept it as the revealed will of God, and therefore infallible; the Liberals and Modernists believe it to be largely, if not wholly, the work of man, and therefore fallible. The former believe it to
be the truth; the latter believe that it
contains truth--but not
all truth--and
also error."
Part I defends the position taken by the Presbyterian General Assembly at its May 1923 session. Part II focuses on evolution, asking the question "shall teachers, paid by taxation, be permitted to substitute the unproven hypotheses of scientists for the 'Thus saith the Lord' of the Bible, and so undermine the faith of the children of Christian taxpayers?"
Bryan concluded the Preface by saying, "Evolution is discussed because it is the root cause of the dissension in both Church and school."
